Abstract

Two major conservation issues face forest licensees working in wet interior cedarhemlock (ICH) forests in B.C. The first of these is the growing international recognition of 'antique forest' stands and their high canopy biodiversity values (especially cyanolichens). Second, the maintenance of habitat for threatened mountain caribou populations is closely linked to the retention of hair-lichens in ICH forest stands. Partialcutting harvesting systems offer one possible means of retaining these values. Our research will examine lichen retention and harvesting intensity in previously established partial-cutting trials. At two sites (Lunate and Minnow) our measurements in 2003 will provide key post-harvest assessments. A third site (Isaiah Ck.) will be established in core mountain caribou habitat, providing comparisons between canopy lichen retention and partial-cutting harvesting intensity in three major forest districts (Robson Valley, Prince George, and Horsefly). These findings will be immediately applicable to forest managers operating in the ICH.
